By Any Other Name Problem

I have changed them and no gems appear

// Change the names of variables to make gems appear!
// Change the name of variable "enemy1" to "chunky".
var chunky = hero.findNearestEnemy();
hero.attack(chunky);
hero.attack(chunky);

// Change the name of variable "enemy2" to "monkey".
var monkey = hero.findNearestEnemy();
hero.attack(monkey);
hero.attack(monkey);

// Collect the gems after changing the variables.
hero.moveUp();
hero.moveRight();
hero.moveRight();
